Abstract
Background and Objective: Natural killer (NK) cells are known to
have an effect on the prevention of tumorigenesis for the initial cancer, as
well as the metastatic cancer. For the past several years, the relationship
between cancer and inflammation has been actively studied in preclinical and
clinical settings, but there are no reports on alterations in and correlation
for NK cell activity (NKA) and systemic inflammatory markers. Accordingly, this
study aimed to measure correlation between NKA and the levels of other systemic
inflammatory markers in patients with gastric, breast, and pancreatic cancer who
received Wheel Balance Cancer Therapy (WBCT). Methods: Forty-two
electronic charts of patients with gastric, breast, and pancreatic cancer
treated with WBCT from February 1, 2015 to September 30, 2015, were reviewed
retrospectively. These charts were statistically analyzed, looking for
alterations of and correlation for NKA and the expressions of systemic
inflammatory markers. Results: Patients with a NKA of under 300
pg/mL at admission showed significantly higher erythrocyte sedimentation rate
(ESR) and neutrophil-to-lymphocyte ratio (NLR) values and decreasing NLR values
due to WBCT than patients with an NKA greater than 300 pg/mL. As a result of the
correlation analysis between NKA and the levels of the systemic inflammatory
markers, NKA showed significant negative correlation with NLR, ESR, and
fibrinogen values. Conclusions: Negative correlation was identified
between NKA and NLR, NKA and ESR, and NKA and fibrinogen in patients with
heterogeneous cancer patients.

Abstract
This study aims to evaluate the effect of neoadjuvant chemoradiotherapy (NCRT) on perioperative immune function during surgery to treat resectable locally advanced esophageal cancer. Records were retrospectively analyzed for 220 patients with locally advanced esophageal cancer, of whom 112 received surgery alone and 98 received neoadjuvant NCRT plus surgery. The two groups were compared in terms of proportions of CD3+, CD4+, CD8+, and natural kill (NK) cells, as well as the ratio of CD4+ to CD8+ cells. These measurements were made using flow cytometry on preoperative day 1 and on postoperative days 1 and 7. Subgroup analysis were performed in terms of degrees of pathological response of NCRT. When the entire NCRT and no-NCRT (surgery alone) cohorts were compared, no significant differences in propocrtions of CD3+, CD4+, CD8+, or NK cells or in the CD4+/CD8+ ratio occurred at any of the three time points. Similar results were obtained using the subgroup of NCRT patients who were NCRT-sensitive, but the subgroup of NCRT-insensitive patients showed significantly lower CD4+ and NK proportions and lower CD4+/CD8+ ratio than the no-NCRT group. Our findings suggest that NCRT does not affect perioperative immune function in patients who are NCRT-sensitive, but it does significantly reduce such function in patients who are NCRT-insensitive.

Abstract
BACKGROUND Neoadjuvant chemoradiation (NCRT) has emerged as a component of the standard treatment for esophageal squamous cell carcinoma (SCC). The primary benefit of NCRT is an improvement in long-term survival; however, the impact of NCRT on short-term outcomes is unclear. METHODS A comprehensive electronic literature search was performed via the MEDLINE (PubMed), Cochrane Library, and Google Scholar databases through November 2015 for the inclusion of randomized controlled trials (RCTs) that evaluated short-term outcomes of patients administered NCRT followed by surgery compared with surgery alone for resectable esophageal SCC. The main outcome measures were postoperative mortality and morbidity. A meta-analysis was performed using random-effects models to calculate odds ratios (ORs) with 95 % confidence intervals (CIs). RESULTS Eight RCTs were included, for a total of 1058 patients. Meta-analysis of the overall postoperative mortality and cardiopulmonary complication rates showed that there was a significant increase for patients administered NCRT followed by surgery compared with surgery alone (OR 1.87, 95 % CI 1.07-3.28, p = 0.03, number of patients needed to harm = 33.3; and OR 2.12, 95 % CI 1.03-4.35, p = 0.04, respectively). Dropout before surgery was higher for patients in the NCRT followed by surgery group compared with patients in the surgery-alone group. NCRT has no statistically impact on anastomosis and other complications compared with surgery alone. CONCLUSIONS NCRT for esophageal SCC significantly increases postoperative mortality and cardiopulmonary complications.

Abstract
Background: CD4+ and CD8+ T cells are the main types of lymphocytes in cell-mediated immunity and play a central role in the induction of efficient immune responses against tumors. The frequencies of T cell subtypes in the peripheral blood and tumor tissues, and draining lymph nodes (dLN) can be considered as useful markers for evaluation of the immune system in cancers. Methods: In this study, the frequencies of CD4+ and CD8+ T cells in blood, tumor tissues, and dLN samples of breast cancer patients were compared with each other and with similar tissues from normal individuals. Immunophenotyping was carried out by flow cytometry and the expression levels of CXCL10, granzyme B, and mammaglobin were evaluated by real-time PCR. Results: In the peripheral blood, there were no differences in the T cell subsets between the patients and the normal individuals. The frequency of CD8+ T cells was significantly higher in tumor tissue than normal breast tissues while granzyme B expression was similar. Based on mammaglobin expression levels, dLN have been classified into micro- and macro-metastatic dLN. We found significantly lower frequency of CD4+ in macro-metastatic dLN than micro-metastatic dLN. CD8+ frequency was similar in both dLN; however, granzyme B expression was higher in micro-metastatic ones. There was not any significant difference in CXCL10 expression between the two types of dLN. Conclusion: Based on our results, although the tumor does not affect the systemic immunity, tumoral cells affect the local immune system in the tumoral tissues and the metastatic dLN.

Abstract
BACKGROUND Immune cells undergo extensive apoptosis in patients with cancer, which may be related to immune evasion by cancerous cells. The present study was designed to investigate the relationship between natural killer (NK) cell apoptosis and Fas expression in gastric cancer patients. METHODS NK cell apoptosis and Fas expression were evaluated by multicolor flow cytometry. Soluble Fas ligand (sFasL) was quantitated by enzyme-linked immunosorbent assay. RESULTS The frequency of apoptotic NK cells in gastric cancer patients was significantly higher than in normal controls (p = 0.0016). Moreover, their frequency was related to the progression of gastric cancer. Fas-positive NK cells were significantly more common in gastric cancer patients compared with normal controls (p = 0.034). Furthermore, Fas expression was closely related to the frequency of NK cell apoptosis (r = 0.6, p < 0.0001). The frequency of tumor-infiltrating NK cell apoptosis was significantly higher than that of circulating NK cell apoptosis (p = 0.035). Furthermore, Fas-positive NK cells in gastric cancer tissues occurred significantly more often than in peripheral blood (p = 0.029). FasL concentration in gastric cancer patients was lower than that in normal controls, and the difference tended to be significant (p = 0.057). Apoptotic circulating NK cells significantly decreased after surgery compared to before surgery (p = 0.023). Furthermore, Fas expression on circulating NK cells also significantly decreased after surgery compared with before surgery (p = 0.021). CONCLUSIONS Upregulation of Fas expression on NK cells is related to increased apoptosis of circulating NK cells in gastric cancer patients.

Abstract
BACKGROUND Although malignant diseases are known to be associated with immune suppression, the detailed mechanisms involved are still unknown. NKG2D is an activating cell surface receptor expressed by natural killer (NK) cells and CD8+ T cells, and the engagement of NKG2D is extremely important for NK cell activation. Although decreased NKG2D expression on NK cells is closely related to immune evasion by some cancers, the immunopathological importance of this phenomenon in gastric cancer patients remains unclear. METHODS NKG2D expression on NK cells was determined, using multicolor flow cytometry, to investigate the mechanisms responsible for immune evasion in gastric cancer patients. RESULTS NKG2D expression on NK cells from gastric cancer patients was significantly lower than that in healthy controls. Also, NKG2D expression in advanced gastric cancer was significantly lower than that in early gastric cancer. NK cells from patients with lymph node metastasis expressed significantly lower levels of NKG2D than the NK cells from those without lymph node metastasis, and NKG2D expression on NK cells in gastric cancer tissue was significantly lower than that of circulating NK cells. NKG2D expression on NK cells obtained from cancer patients was restored after 48 h in culture with RPMI containing 10% AB serum. Furthermore, NKG2D expression on NK cells obtained after surgery was significantly higher than that before surgery. CONCLUSIONS Decreased NKG2D expression on NK cells may be one of the key mechanisms responsible for NK cell dysfunction in gastric cancer.

Abstract
AIM: To observe the clinical effect of acupuncture and traditional Chinese medicine in improving the gastrointestinal function and immune function in patients with intestinal tumors after surgery.
METHODS: One hundred and five patients were randomly and equally divided into three groups: control group, Chinese medicine group, and acupuncture group. The control group received only conventional therapy, while the Chinese medicine group underwent conventional therapy and treatment with Simotang Oral Liquid (three times daily for 10 d), and the acupuncture group underwent conventional therapy and acupuncture (once a day for 10 d).
RESULTS: On day 10 after treatment, the recovery of gastrointestinal function was significantly different among the three groups (F = 18.98, P < 0.05). Compared with the control group and traditional Chinese medicine group, the acupuncture group showed more rapid recovery of gastrointestinal function (both P < 0.05). Compared with the control group and traditional Chinese medicine group, the counts of leukocytes, lymphocytes and neutrophils were significantly improved in the acupuncture group (all P < 0.05). The percentages of CD3, CD4, CD4/CD8 and NK cells differed significantly among the three groups (CD3: 69.44% ± 6.37% vs 57.62% ± 8.08%, 56.57% ± 8.90%, F = 31.25; CD4: 35.63% ± 6.26% vs 30.28% ± 6.66%, 30.89% ± 6.25%, F = 7.42; CD4/CD8: 1.27% ± 0.44% vs 1.01% ± 0.45%, 1.03% ± 0.64%, F = 5.64; NK: 13.29% ± 3.45% vs 11.88% ± 3.89%, 10.64% ± 2.64%, χ2 = 10.39, all P < 0.05). The score of digestive system symptoms and ZPS were also significantly different among the three groups (all P < 0.05).
CONCLUSION: Jiangqi Hewei Tongfu method can promote the recovery of gastrointestinal function and immune function, bidirectionally modulate the numbers of leukocytes, lymphocytes and neutrophils, and thereby improve the score of digestive system symptoms and ZPS in patients with intestinal tumor after surgery.

Abstract
BACKGROUND Resections for esophageal cancer are invasive, with high mortality and morbidity rates. The object of this study was to clarify the factors associated with in-hospital death while also evaluating any associated historical changes in the characteristics of such deaths. METHODS The factors associated with mortality were examined by logistic regression analysis in 1106 patients who underwent an esophagectomy for esophageal cancer. The historical changes in the characteristics of in-hospital deaths were also evaluated. RESULTS A multivariate analysis revealed that not only undergoing an esophagectomy before 1979, but also a patient's age (odds ratio 1.070 for every increase in age by year) and an incomplete resection (odds ratio 2.265) were independent factors associated with in-hospital death. The in-hospital mortality rates were 16.1%, 5.8%, 2.5%, and 3.1%, while the 30-day mortality rates were 9.2%, 2.2%, 0.8%, and 0.3% during 1964-1979, the 1980s, the 1990s, and the 2000s, respectively. Eight patients had preoperative comorbidities among 11 patients who died in the hospital after 1997. The mortality rate was 5.5% in patients with any comorbidities, while it was 1.3% in patients without any comorbidities (P = 0.026). The most common direct cause of in-hospital death was previous pulmonary complications; however, cancer progression has recently become the most common cause. CONCLUSIONS To prevent in-hospital mortality after an esophagectomy, strict indications for surgery and careful perioperative management are important, especially in high-risk patients with advanced esophageal cancer.

Abstract
BACKGROUND In Japan, most esophageal cancers are squamous cell carcinomas, and the results of esophagectomy have improved remarkably in recent years. The object of this study was to evaluate advances in operative therapy for esophageal cancer in Japan. METHOD We evaluated mortality, morbidity, and prognosis in 1000 consecutive patients who underwent esophagectomy for esophageal cancer at a single institution in Japan. The patients were divided into 3 groups according to the period when esophagectomy was performed: Group I (n = 197), 1964-1980; group II (n = 432), 1981-1993; and group III (n = 371), 1993-2006. RESULTS The incidence of squamous cell carcinoma was 94%. The morbidity rates were 62%, 38%, and 33 %, in groups I, II, and III, respectively (P < 0.01, groups I vs II and III), and the in-hospital mortality rates were 14.2%, 5.1%, and 2.4%, respectively (P < 0.01, between each group). The 5-year overall survival rate was 30% (14%, 27%, and 46% in groups I, II, and III, respectively; P < 0.0001). Multivariate analysis revealed age, gender, depth of invasion, node metastasis, distant metastasis, curability, extent of lymphadenectomy, resectability, and the period when the operation was performed as independent prognostic factors. CONCLUSION Generally, esophagectomy has been performed safely without critical complications; however, the prognosis has improved remarkably with advances in surgical techniques and treatment modalities.

Abstract
BACKGROUND The preoperative immunological condition of patients with malignant tumors should be considered in determining the prognosis. METHODS A lymphoblastic transformation test in which lymphocytes were stimulated with phytohemagglutinin (PHA) was performed for 155 patients with esophageal squamous cell carcinoma (SCC). RESULTS Multivariate analysis demonstrated that a lower preoperative PHA response (p = 0.028), as well as the depth of the tumor (p = 0.011), lymph node metastasis (p = 0.0003), lymphatic permeation (p = 0.002), and the incidence of postoperative complication (p = 0.016) were independent factors associated with a poor prognosis for patients with SCC of the esophagus. CONCLUSIONS A suppressed PHA response is an additional significant prognosticator for SCC of the esophagus.

Flow cytometric analyses for peripheral T-lymphocyte subsets showed that the red ginseng powder restored CD4 levels to the initial preoperative values during postoperative chemotherapy. Depression of CD3 during postoperative chemotherapy was also inhibited by the red ginseng powder ingestion. This study demonstrated a five-year disease free survival and overall survival rate that was significantly higher in patients taking the red ginseng powder during postoperative chemotherapy versus control (68.2% versus 33.3%, 76.4% versus 38.5%, respectively, p < 0.05). In spite of the limitation of a small number of patients (n = 42), these findings suggest that red ginseng powder may help to improve postoperative survival in these patients. Additionally, red ginseng powder may have some immunomodulatory properties associated with CD3 and CD4 activity in patients with advanced gastric cancer during postoperative chemotherapy.

Abstract
The cell-mediated immune response of blood lymphocytes from 110 untreated dogs with different tumours was evaluated. The influence of different tumour types on the cellular immune system was examined by assessing the percentage of isolated large granular lymphocytes (LGL), in vitro natural cytotoxicity and mitogen-induced lymphocyte proliferation. Although the overall natural cytotoxicity of dogs with different tumours was decreased, the overall difference from control values was not statistically significant. However, mitogen-induced lymphocyte proliferation was significantly depressed in dogs with tumours in comparison with the controls. Dogs with mammary carcinomas showed significantly lower natural cytotoxicity than controls and dogs with myeloid neoplasms showed significantly lower mitogen-induced lymphocyte proliferation. Abnormalities exist not only in natural cytotoxicity but also in mitogen-induced lymphocyte proliferation. For the dog, this is the first study to assess the influence of different tumours using a combined evaluation of natural cytotoxicity and mitogen-induced lymphocyte proliferation in such a large number of animals.

Abstract
BACKGROUND AND AIMS Advanced neoplastic diseases alter the immune response in cancer patients. The aim of this study was to evaluate the changes of T-lymphocyte subsets during postoperative adjuvant chemotherapy, and the relationship between T-lymphocyte subsets and tumor recurrence in AJCC stage III gastric cancers. MATERIAL AND METHODS Analysis of T-lymphocyte subsets was performed in 39 patients with stage III gastric adenocarcinoma who had undergone a curative gastric resection and postoperative chemotherapy. CirculatingT-lymphocyte subsets were measured on venous blood by using flow cytometry and monoclonal antibodies on preoperative day 1, and postoperative months 1, 3, and 6. RESULTS The 5-year disease-free survival rates of patients with stage 3a and 3b gastric cancer were 57.1% and 33.3%, respectively (p = 0.06). Values of CD3+ and CD4+ T-cells, and CD4+/CD8+ ratios were consistently lower in the recurrence group throughout the observation period. CD4+ T-cell counts were significantly lower in the recurrence group on preoperative day 1, and postoperative months 1 and 6. However, most values of the T-lymphocyte subsets showed no statistically significant difference when comparing the stage 3a and 3b disease patient groups. CONCLUSIONS The results of this study suggest that immunosuppression associated with CD3+ and CD4+ T-cell depression is a risk factor for postoperative recurrence in patients with stage III gastric cancer.

Abstract
Regulation of innate immunity may be an effective means of cancer control. Delaying cancer onset is regarded as an important mode of action in cancer prevention. We have been investigating the chemopreventive mechanisms of Lactobacillus casei Shirota (LcS), a probiotic strain. In this study, we evaluated the effect of LcS on tumor onset and the involvement of natural killer (NK) cells using a 3-methylcholanthrene-induced carcinogenesis model. C3H/HeN mice were divided into three groups, according to treatment: vehicle-treated, treated with vehicle only; control, 3-methylcholanthrene treated; LcS, 3-methylcholanthrene and LcS treated. 3-Methylcholanthrene was injected intradermally at 7 weeks of age. LcS was mixed into the diet (0.05%, w/w), which the mice were fed from the day of 3-methylcholanthrene injection onward. Tumor incidence was observed weekly. Profiles of splenic NK cells, in vitro cytotoxicity and the proportion, in the early stage of carcinogenesis were analyzed at 5 weeks after the injection. The tumor suppressive effect of LcS was also evaluated in a beige mouse model that is genetically deficient in NK cells. LcS delayed tumor onset and reduced tumor incidence in the results with C3H/HeN mice (P< 0.05). More specifically, tumor incidence in the control group was 33% at 6 weeks after the injection and 83% at 11 weeks as opposed to 0 and 42%, respectively, in the LcS group. NK cell cytotoxicity was significantly higher than in the control group, and the number of NK cells also increased in the LcS group of C3H/HeN mice. However, LcS failed to suppress tumorigenesis in the beige mouse. These findings suggest that enhancement of the cytotoxicity of NK cells by LcS delays tumor onset.

Abstract
OBJECTIVE Natural cytotoxicity, mediated by natural killer (NK) cells, has been believed to play an important role in inhibiting experimental tumor metastasis, and diminished NK cell activities leads to a high incidence of tumor occurrence. Despite convincing evidence from experimental studies, the role of NK cells in the immunological surveillance against cancer in human is poorly defined. METHODS The present study was based on a retrospective analysis of data on 156 patients with gastric cancer, who were surgically treated in the Department of Surgery II, Kyushu University Hospital from 1993 to 1996. All patients were examined for NK cell activity based on a peripheral blood sampling done preoperatively. RESULTS Significant association between NK cell activity and clinicopathological parameters including tumor size, lymphatic involvement, vascular involvement, and lymph node metastases was evident. When comparing the two groups according to NK cell activity, tumors with low NK cell activity tend to have lymphatic involvement. The 5-yr survival rates were 94.6% and 72.3% for those with NK cell activity > 25% lysis and < or = 25% lysis, respectively, the value being statistically significant (p < 0.05). The independent risk factors for prognosis examined by logistic regression analysis were lymphatic involvement. NK cell activity, depth of tumor invasion, and lymph node dissection. CONCLUSIONS These current data showed that NK cell activity may be related to tumor volume and dissemination. Measurement of preoperative NK cell activity may be pertinent for the prognosis of patients with gastric cancer and for follow-up clinical management.

Abstract
BACKGROUND Cancer patients have often been reported to have impaired immune function, and the effect of treatment modalities, such as surgery, irradiation, and chemotherapy, in depressing patients' immunity has also been reported. In this investigation, the effect of treatment on the cellular immunity of esophageal cancer patients was evaluated. METHODS Immunological parameters, such as natural killer (NK) activity and lymphocyte subsets in peripheral blood, were measured in 32 esophageal cancer patients on 5 occasions (on the day of admission, 2 days before surgery, and 1 week, 1 month, and 2 months after surgery). RESULTS NK activity was greatly impaired shortly after the operation, and the percentages of lymphocytes as a whole, and CD8+, CD16+, and CD57+ lymphocytes were significantly decreased, on the other hand, a postoperative increase in the CD4+/CD8+ ratio was observed. No significant depression of immune function by postoperative irradiation was observed. CONCLUSIONS The results of this study suggest that cellular immunity, especially cytotoxicity, shortly after esophagectomy may be greatly impaired by the surgical stress of esophagectomy and an added effect of chemotherapy.

Abstract
The aim of this study was to assess monocyte/macrophage function, as defined by lipopolysaccharide (LPS)-induced production of tumour necrosis factor (TNF)-alpha, interleukin (IL)-10 and interferon (IFN)-gamma by stimulated whole blood cultures in patients with colorectal carcinoma before and after surgical resection. Forty colorectal cancer patients prior to surgery and 31 healthy controls were studied. Heparinized venous blood was taken from colorectal cancer patients prior to surgery and from healthy controls. Serial samples were obtained at least 3-6 weeks post-operatively. Blood was stimulated with LPS for 24 h and supernatants were assayed for TNF-alpha, IFN-gamma and IL-10 by enzyme-linked immunosorbent assay. LPS-induced production of TNF-alpha and of IFN-gamma was reduced in patients with colorectal carcinoma compared to controls (TNF-alpha, 11,269 pg/ml(-1) ¿12,598¿; IFN-gamma, 0.00 pg/ml(-1) ¿226¿; median ¿IQR¿) (TNF-alpha, 20,576 pg/m(-1) ¿11,637¿, P < 0.0001; IFN-gamma, 1,048 ¿2,428¿, P = 0.0051, Mann-Whitney U-test). Production in patients after surgery had increased (TNF-alpha: 17,620 pg/ml(-1) ¿7,986¿; IFN-gamma. 410 pg/ml(-1) ¿2,696¿; mean ¿s.d.¿) and were no longer significantly reduced when compared to controls (TNF-alpha, P = 0.28; IFN-gamma, P = 0.76). Production of TNF-alpha and IFN-gamma prior to surgery were reduced to a greater extent in patients with Dukes' stage C tumours compared to those with Dukes' stage A and B stage. There was no difference in IL-10 production between any group. Monocytes/macrophages from patients with colorectal carcinoma are refractory to LPS stimulation as reflected by reduction in TNF-alpha and IFN-gamma production and this is more pronounced in patients with advanced stage tumours. This suppression is not mediated by IL-10 and disappears following surgical resection of the tumour. This provides evidence for tumour induced suppression of immune function in patients with colorectal cancer and identifies a potential therapeutic avenue.

Abstract
BACKGROUND AND OBJECTIVES En bloc esophagectomy has been established as the treatment of choice for patients with resectable esophageal carcinoma. However, an extensive surgical procedure may result in further impairment of the patient's nutritional status and immune system. Thus a prospective study was undertaken to evaluate the perioperative sequential changes in patients' nutritional and immune status and the timing to institute postoperative adjuvant therapy. METHODS Thirty-seven patients (34 male, 3 female) who had undergone en bloc esophagectomy with gastric institution for epidermoid carcinoma of the esophagus were studied. The mean age was 62.3 years. The nutritional and immune assessments were performed preoperatively, on the third postoperative day, in the first week, second week, third week, and at the end of the first and third month. The biochemical studies for nutritional evaluation included serum albumin, cholesterol, iron, transferrin, magnesium, zinc, total iron binding capacity (TIBC), and nitrogen balance. Evaluation of the immune status consisted of: (1) total lymphocyte count, (2) lymphocyte subpopulation, (3) immunoglobulins, (4) complements (C3 and C4), (5) lymphocyte blastogenic responses, (6) tumor necrosis factor-alpha and interleukin-2 secretion activity from mononuclear cells, and (7) C-reactive protein (CRP) level. RESULTS All the parameters in nutritional assessment declined profoundly by the third postoperative day (P < 0.05). The most severe deterioration was in serum iron, followed by transferrin, TIBC, cholesterol, and zinc. Most of them returned to the preoperative levels within 2-3 weeks after surgery. However, the serum levels of iron, transferrin, and TIBC required a longer period of time (> 1 month) to return to normal. A remarkable increase of serum CRP was detected in the first postoperative week (P < 0.05), but immunoglobulins and complements decreased significantly yet variably (P < 0.05) in the second or third postoperative week before gradually returning to preoperative levels. Moreover, during the first week after surgery, CD3 and CD8 diminished following esophageal surgery, whereas CD20, CD4/CD8 ratio, and lymphocyte blastogenic responses increased significantly (P < 0.05). CONCLUSIONS Except for iron-related parameters, all the other nutritional parameters returned to the preoperative level by the third postoperative week. An adequate supplementation of iron and protein for 1-3 months after surgery is needed. En bloc esophagectomy might have only a mild and temporarily adverse effect on the host immune defense. Regarding the postoperative recovery of a patient's nutritional and immune status, postoperative chemo-radiotherapy is optimally instituted after the third postoperative week, instead of within 2 weeks of surgery.

Abstract
PURPOSE It has recently been reported that CD4+ T-lymphocytes are reduced in advanced colorectal cancer patients. However, it is not clear whether such changes in T-lymphocyte subsets are an early or late event in such patients. The aim of this study was to examine the relationship between these subsets and disease progression in colorectal cancer. METHODS Flow cytometric analysis of T-lymphocyte subsets was performed in 39 patients who, approximately 12 months previously, had undergone surgery for colorectal cancer. These patients were grouped according to whether they developed a recurrence in the following two years. A group of healthy subjects was studied as controls. RESULTS There was a significant increase in the median neutrophil count (4.3 vs. 3.7 10(6)/ml) and the median numbers of platelets (282 vs. 216 10(6)/ml) of the recurrence group compared with the control group, respectively (P < 0.05). The median numbers (0.28 vs. 0.73 10(6)/ml) and percentage (29 vs. 38 percent) of CD4+ T-lymphocytes of the recurrence group were significantly reduced compared with that of the control group (P < 0.05). There were also reductions in the median percentage of CD3+ cells (67 vs. 74 percent) and the median numbers of CD4+ T-lymphocytes (0.28 vs. 0.46 10(6)/ml) of the recurrence group compared with the no recurrence group (P < 0.05). CONCLUSIONS Reduction of CD4+ T-lymphocytes occurs before detectable recurrence of colorectal cancer. Results of the present study are consistent with impaired immunity, as measured by such lymphocyte subset populations, being important in tumor recurrence in colorectal cancer.

Abstract
BACKGROUND Natural cytotoxicity, mediated by natural killer (NK) cells and cell with lymphokine-activated killer (LAK) activity, is believed to play an important role in host anti-cancer mechanisms. METHODS The authors critically review recent publications on the role of natural cytotoxicity in patients with cancer. RESULTS In patients with cancer, several studies have noted variations in the numbers and activity of NK and cells with LAK activity in different body compartments. NK cell activity in the peripheral blood lymphocytes (PBLs) is higher than that found in lymph nodes and within tumors, and this appears to be due to the presence of suppressor factors. The natural cytotoxicity of PBLs in patients with different types of cancers varies. However, there appears to be a trend for natural cytotoxicity to be reduced in certain cancer patients, possibly related to tumor volume or dissemination. Anti-cancer treatments (e.g., surgery, hormonal modulation, radiotherapy and chemotherapy) can also result in suppression of natural cytotoxicity, although the long-term effect on response to treatment and development of metastases is at present unknown. CONCLUSIONS NK and LAK cells, through the use of immune biologic modifiers, have been demonstrated to have a therapeutic role in the treatment of human cancers. Further studies are required to determine the optimal dosages and combinations of chemotherapeutic agents, the timing of surgery, and the adjuvant use of immune biologic response modifiers. An increasing awareness and understanding of this field, may allow for the future development of anti-cancer therapies.

Abstract
Sixty-five consecutive, locally advanced esophageal cancer patients were treated by the West Side Medical Center Esophageal Service at the Cook County and University of Illinois hospitals. Each patient was prospectively evaluated with multiple endoscopies including esophagogastroduodenoscopy, bronchoscopy, nasopharyngoscopy, and laryngoscopy. Twenty-four patients (37%) had endoscopic findings that significantly altered therapeutic regimens. Patients identified as having an obvious or impending esophageal fistula or poor performance status were treated in a palliative fashion. Forty (61.5%) patients were considered candidates for treatment with multimodal therapy which included radiation, chemotherapy, and surgery. There was a response rate of 82.5% and a 1-year disease-free survival of 88.9% which was statistically significant when compared to the other patient treatment groups. These data illustrate the necessity of multiple endoscopic evaluation of locally advanced esophageal cancer patients for stratification into appropriate treatment groups. Aggressive treatment afforded selected patients excellent relief of presenting symptomatology, as well as an improved, more acceptable, disease-free survival.
